I developed a PHP library for all WordPress plugin and theme authors. With this library you can easily manage your updates and send notification to your customers when update is available. Your customers can download their update from wp-admin panel.
Customers can postpone this warning to remind later or disable the warning forever.
All installation and usage details on my GitHub page.
- A little panel to users update their purchase code.
- UI improvements
I’m waiting your feedbacks.
Thank you and good luck with sales.
